It is up to you. There is no disadvantage to bidding on an employer for Regionals, since you use separate bids than you do for OCI. In addition, if you do not receive the Regional bid, you have the opportunity to bid a second time for the same employer through OCI. You will have 30 bids for the Regional Interview program and 60 for OCI. One advantage a student has by participating in Regionals rather than interviewing through OCI is demonstrating a commitment to the market
In addition, please note that while you are not prohibited from bidding for a firm for OCI that you have already bid for in connection with the Regional Interview Program, even if the firm specifies “no multiple interviews”, if a “no multiple interview” firm contacts us and requests that we remove students they have already met with through the Regional Interview Program from their OCI schedule, we must do so. Therefore, you must carefully consider which office of the firm in question you prefer. If, for example, you truly prefer the New York office of a firm, which is interviewing on campus, you need to be aware that bidding on and interviewing with the firm through the Regional Interview Program could potentially result in your preclusion from interviewing with the New York office on campus.
